A sealing lid and cup container assembly for storing and dispensing comestibles is disclosed wherein the seal is maintained during pressure and vacuum forces. The container includes a cup formed of a frusto-conical sidewall and a bottom wall secured to the sidewall at one end thereof. The sidewall has an outwardly extending and rolled rim at the periphery of its other end defining a circular opening, and a first continuous sealing ridge extending inwardly of the rim. The container also includes a circular lid which is configured and dimensioned for snap-fitting sealing engagement with the cup at its first end such that, when the lid is snapped onto the cup over the opening, the lid includes a flat circular panel having along its periphery an outer wall member which has a second continuous sealing ridge positioned for cooperative sealing engagement with the first continuous sealing ridge of the cup at at least two points of cross-sectional contact so as to provide a first internal sealing of the cup. The lid also has an annular hollow rib which is secured to the outer wall member and is positioned over the rim of the cup. A third continuous sealing ridge on the rib extends outwardly toward and sealingly contacts the rim at at least one point of cross-sectional contact so as to provide a second sealing of the cup.
